This model simulates groundwater dynamics in the Pleistocene aquifers of the Lower Rhine lignite mining area (Germany). GROWA uses an area-differentiated approach to calculate recharge rates depending on runoff-relevant site characteristics, which are represented by a set of baseflow indices. The regional accuracy of the coupled groundwater and GROWA models has been checked using groundwater hydrographs as validation criteria. The results suggest that the current (unadjusted) version of GROWA underestimates the regional groundwater recharge rate by 10-20 mm/yr. The comparative analysis identified areas where recharge calculations could be improved by adjusting the baseflow indices for areas where runoff is dominated by slope, low water-logging and a low degree of sealing. Using the adjusted set of baseflow indices, the mean groundwater recharge rate of the Rurscholle region was modelled as approx. 170 mm/yr. This study highlights the benefit of using a coupled approach and being able to independently calibrate and validate groundwater recharge boundary conditions in regional groundwater models.}, language = {en} } @inproceedings{CeranskiJahnkeVoigt, author = {Ceranski, H. and Jahnke, Christoph and Voigt, Hans-J{\"u}rgen}, title = {Klarwasserentsorgung (und -nutzung) im Spannungsfeld von Grundwasserschutz, Naturschutz und Landschaftswasserhaushalt}, series = {Grundwasserressourcen im Spannungsfeld zwischen Erschließung und Naturschutz, Fachtagung der Fachsektion Hydrogeologie der DGG, Greifswald 9. - 11.
